Scientists Uncover Why Chang’e-6 Lunar Soil Is “So Sticky”

Researchers at the Institute of Geology and Geophysics, Chinese Academy of Sciences, have identified the physical mechanism behind the unusually high cohesiveness of lunar soil collected by the Chang’e-6 mission on the Moon’s far side. High-resolution CT scans revealed extremely fine, rough, and irregular particles with a D60 of just 48.4 micrometers. Enhanced friction, van der Waals forces, and electrostatic forces jointly increase cohesion, offering new insights for future lunar exploration and base construction.
